Could not build wheels for xformers, which is required to install pyproject.toml-based projects (macOS)

I am trying to install the audiocrafts library in my pyenv virtual environment (MacOS) but I keep getting this error.

    clang: error: unsupported option '-fopenmp'      error: command '/usr/bin/clang' failed with exit code 1      [end of output]  note: This error originates from a subprocess, and is likely not a problem with pip.  ERROR: Failed building wheel for xformers  Running setup.py clean for xformersFailed to build xformersERROR: Could not build wheels for xformers, which is required to install pyproject.toml-based projects

If I try to install xformers using pip, I still get the same error as above. What am I missing out on?
